Now, both interarrival time and service time distributions are allowed to be general.? In general, average performance measures (waiting time in queue, number in queue, etc) can be very well approximated by mean and variance of the distribution (distribution shape not very important).? This is very good news for managers: all you need is mean and standard deviation, to pute average waiting timeQueue ApproximationInputs: S, ?, ?, (Alternatively: S, ?, ?, variances of interarrival and service time distributions)演講完畢，謝謝觀看
